MHD teases N54 Antilag with the stock DME

[Jake@MHD]

Has anyone here had the no/low boost issue on an OTS map? Can't seem to get debug files from anyone, they complain on FB then disappear).

Need someone who:
1. flashed an OTS map using app version 3.03 (or later if an update comes out in the mean time)
2. did NOT incorrectly select an ECA preset (hardware ECA kit) that they don't actually have installed
3. has little to no boost (symptom should be around 5psi / 110 load max)

 

[Jake@MHD]

And those with the "no audio" after map switching with the wheel controls, what year and model are your cars?

Zero to 60 has done a video on anti lag

agree with him it’s more useful big single cars
this will help the big cars at the track and we might yet see more cars the 9s On the quarter and roll racing…. @Brule have you tried it yet.
?

Mine makes enough torque without antilag, it can smoke the tyres at 40kmph in 2nd gear with a powerglide transmission.

I have used the jb4 antilag and it just does massive powerskids and smoke show.

When I had the precision 7675 it needed it but with a 6466 it makes plenty of power down low.

I'm still running a BQ tuning map from 2 years ago and this morning after successfully running the updated flash with antilag, I can't make more than 9 lbs of boost. I'm usually at 21-22. If I use antilag, I can get it to 15-16. Nothing is loose under the hood and there are no error codes. ??? Lost...

Hi, in the MHD app can you please open the side menu and hit "Send Debug Files." Make sure your phone is connected to the internet for this, and wait until it finishes. After it's done, if you could please PM me your tune file and let me know what email address you use for MHD.

Guys, who can advise on futher. Is anything changed appropriately? How to make 3D boost ceiling work smoothly? @Jake@MHD

@Sava666 both logs look great! What mods do you have?

Log looks ok/safe. I didn’t look at the bin but you should move load target per gear higher/out of the way to stop the throttle closures.

Stockers on fbo. 93 oct. Nothing much, but I wish I could have more understanding of boost ceiling. You can see its fluctuate badly once gear changes and during boost and ceiling doesn't ceil. Which never happend before mhd_switch_maps. Since I'm not a native speaker its sometimes hard to understand some things. Looking for some hints. Self tuning.

Thanks. Already moved my loads bit higher. That strange behavior when changing gears (boost going above ceiling) is what makes me curious? Anyone else having this issue?

Also, scaling should go like this? (I read that this is patched in xdf)

Yes pretty much everyone has this issue. I recommend saving your time and gas money and moving on yours are not bad at all. It is usually masked on stock turbo cars running closer to redline then end up at their higher boost target post shift so it “looks” good. The wastegate just can’t dump boost faster than the DME can pull timing/shift. So the engine is then suddenly ingesting much less air. If you stop the timing from being pulled during shift it gets much better using “Drag mode” in xhp but I don’t recommend anyone use that feature over much more than stock power. There are other ways to calm it down further but all are compromises in one way or another.

 

[Jake@MHD]

Yea, post shift boost spikes are (unfortunately) fairly normal. Once the smoke clears from this initial release, I may look into adding a "wgdc during shift" table that people can use to try and fix this in an easier manner.

 

[Sava666]

Thanks for clarification.

After the update and cold start enabled again my car suffers some difficult starts when the car it at temp.
Any more people experience the same?
Flex fuel custom tune btw.

 

[Beem335i]

Anyone else getting mixture 1 and 2 codes on new update? Also the MHD app monitor keeps disconnecting and reconnecting every 20-30 seconds, I am using iOS version.

Only getting these mixture codes on V10. Other maps are fine.

same. I turned on cold start noise reduction and that helped slightly but it still takes a second or two bumps to get it started, even when priming the pump before hand.

FlexFuel or no? What octane map are you running?

 

[Beem335i]

No flex fuel, using 91 oct v10 map.

I went back to v10 again, mixture codes are gone, might have been the chevron station I filled up at. Also not sure why my MHD App keeps disconnecting and reconnecting when I monitor live, I will try uninstall and reinstall see if that fixes things.
